3 Claims.

'This invention relates to cooling systems and particularly to a coolingapparatus primarily adapted to be used for cooling the passengercompartment of an automobile.

the passenger compartment of the motor vehiclein a novel manner.Further, the invention has for its object to provide a cooling system inwhich the evaporative action of the liquid or moisture content of thecombustible mixture, in passing through the intake manifold, is utilizedto absorb heat from an air stream to cool the same for subsequentdelivery to the passenger compartment.

Fig. 'I is a, fragmentary view, partly in section, of a constructionembodying another form of the invention. l

Referring to Figs. 1, 2 and 3, an internal combustion engine I isprovided with an intake mani- 45 fold 2, carburetor 3 and throttle 4.The engine is mounted in a conventional manner in a. motor vehiclehaving a passenger compartment 5.

Separating the passenger compartment from the internal combustion engineis a dash board or 50 other suitable partitioning means 6 which isattached in the usual manner, to the cowl and the chassis frame 8 andextends therebetween.

Mounted within the passenger compartment,

preferably in a suitable and convenient position 55 above the floorboards, is a cooling unit or mem- Because oi' the particularconstruction of auto- In the particular embodiments of the inventionber9 which comprises a casing I0, a core I I within said casing, and meansfor supplying an air current, such as a motor l2 and a fan I3 positionedwithin the casing and connected thereto, said fan being used to createor provide an air 5 current for passage over the cooling coil and oninto the passenger compartment to cool the passengers. The cooling unitmay be attached to the dash in the desired position by any suitablemeans such as bolts or studs as shown at I4. 10

The cooling core or coil Il within the casing I0 may be formed in acontinuous series of U-shaped bends I5 and is disposed in the front ofthe casing, as shown in Fig. 2. By placing the coil within the casing inthis manner a maximum amount of l5 cooled surface is provided and hencemore cooling of the air which .passes over these coils is effected.

'I'he casing may be Vconstructed of thin sheetA metal and is preferablycylindrical in shape, deep enough to house the coiled or looped core andthe fan I3. 'I'he .front end of the casing may be formed with acircumferential ange I6 to which a protective wire mesh, net or othersuitable screen-like structure I1 may be attached. The casing is shownattached to the motor housing in any conventional manner, as at I8. Thefan I3 is attached to the drive shaft I9 of the motor I2, preferably ofthe suction type, as illustrated in Figs. 1, 2 and 3. This suctionoperated motor is constructed onA the turbine principle wherein a streamof uid, which in this case is air, impinges a series of vanes or blades20 on shaft I9 to cause rotary motion. At a point on the outerperipheral portion of the casing is a port 2l which acts as a nozzle andconnects the inside of the casing to the atmosphere. The port is in sucha position that any uid passing through said port will impinge in jetform the vanes 20 of the turbine ,wheel 22.

The motor housing is connected by a duct 23 to 40 a suitable source ofsuction, such as the intake manifold 2 of the internal combustion engineI; the duct 23 may be opened and closed by means of valve 24. Thus, theinside of the casing can be subjected to a pressure less thanatmospheric. Because of the pressure differential between the inside andthe outside of the casing brought about aooasio When the acceleratorpedal 31 is operated, both the valves will be opened to the properdegree. in this manner the throttle valvel will admit only enough air tobring about the most efllcient evaporation of the .gasoline mixture, andat the same time, the valve 32 will admit additional air to the manifoldin quantities suiilcient to insure the normal operation of the engine.Y,

Although only'the preferred forms of the invention have been shown anddescribed in detail, it will be apparent to those skilled in the artthat the invention is not so limited, but that various changes may bemade therein without departing from the spirit of the invention or thescope of the appended claims.

What is claimed is:

i. In a motor vehicle having a passenger compartmen a cooling. systemforthe passenger compartment comprising, in combination with the and thecarburetor o! the` ln` ternal combustion engine of the motor vehiclepower plant, a cooling member having an inletJ connected to thecarburetor and an outlet connected to the intake side of the engine,means for admitting air to the carburetor to partially form acombustible mixture, such mixture passing through said cooling member onits way to the engine tp effect `a cooling of said cooling member by theevaporative action of the mixtureas it passes through said member, meansfor admitting anadditional quantity of air to such mixture between thecooling member and the intake manlfold to complete the formation of thecombustible mixture, and means for directing an air stream over thecooling member for discharge into the passenger compartment.

2.A 'I'he method of cooling the passenger compartment of an automotive'vehiclehaving an inintake manifold ternal `combustion engine as itsmeans of propulsion, which consists inv admitting a quantity of air tothe engine carburetor to partially form a combustible mixture, lcausingsuch mixture to ilow through a,cooling member tothe intake side of theengine whereby to absorb the heat from said cooling member by theevaporative action of the liquid particles contained in such mixture,adding an additional quantity of air to such mixture between the coolingmember and the intake side of the engine to complete the formation oithe combustible mixture, and causing an air stream to pass over thecooling member and into the passenger compartment.

3. In a motor vehicle having a passenger compartment, a cooling systemforV the passenger compartment comprising, in combination with theintake manifold and the carburetor of the internal combustion engine ofthe motor vehicle power plant, a cooling member having an inletconnected to the carburetor and an outlet connected to the intake sideof the engine, means for admitting air to the carburetor to partiallyform a combustible mixture, such mixture passing through said' coolingmember on its way to the 'engine to effect a cooling of said` coolingmember by the evaporative action ofthe mixture as it passes throughsaidmember, means for admitting an additional quantity of air to suchmixture between the cooling memberand the intake manifold to completethe formation of the combustible mixture, means for controlling theadmission of air through both of the aforesaid means, and means fordirecting an air stream over the coollng member for discharge into thepassenger compartment.
